シーカ・ジャパン List of Products and Services

Both hydrophobic and hydrophilic water-stopping materials play important roles, and the "Sika Inject Hydro Series" offers both of these options. "Sika Inject Hydro A" reacts well with moisture and water, forming an independently foamed semi-rigid solid that exhibits excellent water-stopping effects. As a one-component hydrophobic type, it has good injectability, is less susceptible to alkaline degradation from concrete, and boasts superior durability. The one-component hydrophilic type "Sika Inject Hydro L" also offers good injectability and, through foaming and surfactant action, penetrates well into gaps, cracks, and voids in the ground, strongly adhering to soil particles. **Features of Sika Inject Hydro A** - Outstanding water-stopping effect due to the ability to penetrate even fine gaps under expansion pressure. - Excellent durability, with effects lasting for an extended period. - Hydrophobic, and the solid remains stable without swelling when immersed in alkaline conditions (pH 13) at 60°C. *For more details, please download the PDF or feel free to contact us.*
